So im wondering whether to commit to a new AEG build. I closed my eyes and randomly picked from the rack my JG Steyr AUG A1. Wondering if this might be a bridge to far given its unique layout?
Has anyone done the same? Any build info would be great.
Inside they are basically a v3, with an aug specific trigger system which really doesnt change the function of the box, just overrides the semi auto electronically with a second switch.
Being a JG, the airseal is usually top notch, the tappet spring can do with shortening or changing to a shorter stronger item, the stock piston is worth changing to a better shs or equivalent, but keep the stock piston head, they are great. The gears are classic cast lottery, may handling a larger spring, my not. I would change them to shs. Now the real beauty of JGs, their motors are very good, weaker neo magnet motors, with decent torque and speed. 16:1s will give them a slight boost, 13:1s will get them up around 24-25rps with a snappy semi. an m100 or m110 spring is worth doing, pick you power output.
Also, a good washer and 6mm bolt in the spring retainer to keep in straight in the gearbox is worth doing when upgrading the spring, as the retainer tends to wobble a bit.
basically, gears, spring, tappet spring, and piston, done. You likely won’t want for more, especially if you opt for 13:1s and m110 as you will be hurling gels 24-25 times a second at 360-380 fps. Wild, as most JGs are with the same upgrades.
Worth noting, the mag terminals, and trigger switch are best removed for for any operation, and does require desoldering, and on the mag terminals, take photos, there are a few components and can be painfull to line up and reinstall, especially if you wish to avoid a short.
Thanks @RokSolid I have purchased a spare gearbox and your suggested parts in the Ausgel 70% off sale. They were out of stock for the SHS gears so I purchased the Prometheus 16:1 high speed set which I hope will do the job with a M100 spring and SHS 14 tooth piston. Watching the mailbox so I can get into the internal upgrades. The advice in this Forum is awesome.
I have been doing mine up, have had very little spare time for it and am nearly done but…
It has been a while since I have worked on one. Long enough to forget how much of a dick getting the gearbox together is. The V3 trigger is tricky, but combined with the trigger switch not being screwed in and the mag terminal assembly being a prick… Tenacity is required. And patience.
Also best to not pull it apart and then get busy leaving it in a box in pieces for nearly a month before getting it back together!
I didn’t change the tappet spring or shorten it, the one in the box seemed pretty tight and good.
I also didn’t change the piston, but I did super strength epoxy the rack in. I have loads of JG pistons so why not see how it goes.
I have 13:1 gears and a t238 brushless 25k motor, will run an 11v lipo and m100 or m110 depending on the field and how it performs… could also run an m90 and 7v titan brick. Not a lot of battery space so making the best of what is there.
I used an aoe pad and radiused the gearbox… haven’t seen a lot break but why not try and prevent needing my spare gearbox.
I went with 25k brushless and 13:1 purely to be as efficient and quiet as possible. It won’t be mental rps, should bearound 25.
Also used bearings on the bevel and top of spur, bushes elsewhere. Trying to reduce the gearbox noise as it is right next to your ear!
16:1 will give a little boost in rof, but not make it too crazy for the long barrel in them.
The ausgel sale was pretty handy!
